IMPORTANT: After the first 4 and 8 hours of operation, retighten all wheel attaching nuts. Check tightness of these nuts frequently.

The crop sprayer may be fitted with various tires and wheels. Verify that the combination of tires and wheels and tire pressure is suitable for the speed and load at which the work is done.

There are wheels with 8-bolt wheel connections. The rim and disc of the wheels are completely welded around for high strength. Some tires are available with 40- and with 50 km/h wheels. However, the maximum load which may be carried at these speeds by the tires (and wheels) is limited and should be taken into account!

The following pages explain the meaning of various indications and technical specifications on the tires.

The tire load capacity is indicated by a Load Index corresponding with a standard speed of 40 km/h (speed symbol A8) and a specific reference pressure (indicated by one or more asterisks).

If possible, a second (and third) load capacity is given corresponding with another speed, viz. 10 km/h (A2) or 50 km/h (B). The tire pressure is then not standard-based, but has been given by the tire manufacturer.

The reference pressure is given as follows:

Example:

Tire indication 153A2/142A8 **** means:

142 A8: Load capacity of 2650 kg at 40 km/h and a reference pressure of 3.6 bar.

153 A2: Load capacity of 3650 kg at 10 km/h and a tire pressure of 4.4 bar, according to Kléber.

In the case of lower tire loads, lower tire pressure rates are permissible (see "Tires technical specifications" in this section for the relation between load capacity and tire pressure of the tires in question). If the maximum driving speed is lower than the speed indicated, the tire load may be increased (see load capacity variations according to E.T.R.T.O. standard). However, the tire pressure must then be adjusted.
